Abstract of the Disclosure The apparatus of the instant invention includes a surface traversing mobile frame which, in the preferred embodiment, transports the elements of the invention. Means for dispensing a continuous length of hollow sheath and for dispensing a continuous length of signal-transmitting cable are provided. An assembly table for inserting the cable into the interior of the sheath includes a device for dividing a side of the sheath. Devices for forming a subsurface trench and for training the assembly produced by the assembly are mounted on the frame. The method of the invention includes opening the side of a hollow sheath along its length, and directing a cable into the opening to produce an elongate, continuous assembly of sheath having the cable inside of it. The wall of the plastimer sheath is permitted to assume a non-joined, closed condition along the region previously opened. A trench is formed to receive the assembly and the assembly is subjected to bending as it travels into the trench, the non-joined condition of the sheath accommodating distortion and flattening of the sheath of the assembly during such bending. The sheath is then placed in the trench.
